4.4     Waste Collection
It is proposed to utilise Council’s on-street waste collection service with a bin storage for each unit
located within the basement. Residents will transport their own bins to the kerbside for collection via
Mill Street. The bin store has been integrated into the basement to ensure easy access for residents
and screening from the street.




5.0 FLOOD IMMUNITY

Council flood modelling indicates that the site is subject to inundation in a range of flood events.
See Fig. 4 Below.

A current Council Flood Search can be found in Appendix C and determines that Defined Flood Level
is 2.4m AHD across the site. The Applicable Minimum Floor level is 2.7m AHD to achieve the
minimum 300mm freeboard requirement, and the proposed development achieves the minimum
finished floor level accordingly. Provision of flood immunity for the basement is via a Flow Defence
Flood barrier system or similar. This type of passive system is a self-activating flood barrier that
utilises a float within a channel/chamber that is installed below ground level. It does not require
electricity or manual activation. As the chamber fills with flood water the barrier rises effectively
sealing the installation. The installation is shown on the Engineering Drawings with the remainder of
the driveway area protected from inundation by continuous impervious core filled block walls that
extend to minimum 2.7m AHD. Further details on the Flow Defence system can be found in the
Architectural Plan set.
